PETER JORGEN$ON, OF CHICAGO, ILLINOIS.

SUPERHEATIN Gr STEAM-GENERATOR.

Application filed October 3, 1912.

To all whom it may concern Be it known that I, PETER JORGENSON, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inSuperheating Steam-Generators, of which the following is aspecification.

This invention relates to improvements in steam generators of thesuper-heating type, and it consists in certain peculiarities of theconstruction, formation, arrangement and operation of the various partsthereof, as will be hereinafter more fully set forth and specificallyclaimed.

The principal object of the invention is to provide a steam generator ofthe above named class, which shall be simple and inexpensive inconstruction, strong, durable, and eflicient in operation, and so madeand with its parts so arranged with respect to one another as to presentas large a surface as possible (and a great deal larger surface thanheretofore afforded in generators of this type), to the action of theheat, thereby using the heat to the best advantage in generating steamand re-heating or super-heating the same, and without material loss ofheat.

Another object of the invention is to provide a super-heating steamgenerator which shall comprise a series of groups of conduits, soformed, constructed and arranged with respect to one another, and withrespect to fuel burners, that heat from the said burners may be appliedindependently to one or more of said groups.

Various other objects and advantages of the invent-ion will be disclosedin the subjoined description and explanation.

In the accompanying drawing which serves to illustrate an embodiment ofthe inventionFigure 1 is a side View in elevation of a super-heatingsteam generator, and Fig. 2 is a cross sectional view taken on line 2-2of Fig. 1, looking in the direction indicated by the arrows.

Like numerals of reference refer to corre sponding parts throughout theviews of the drawings.

The reference numerals 5, 6 and 7 designate as wholes the lower groupsof conduits of the generator, and the numerals 8, 9 and 10 indicate aswholes the upper groups of conduits of the apparatus. Each of the saidgroups includes a series of conduits 11, which Specification of LettersPatent.

are by preference rectangular in cross sec tion, as shown, and in useare usually located in parallelism with one another and horizontally,but their positions may be otherwise or varied. The conduits 11comprising each of the groups are spaced apart and arranged in staggeredrelation to one another. The lowermost conduits or conduit of each ofthe lower groups has communication with the conduit or conduits 11thereabove through a hollow connection 12, which unite headers 13, atthe ends of the conduits. Each of the headers 13, at one end of thelower conduits 11, of each of the lower groups has communication with apipe 1 1, which leads to a supply of water, and each of these pipes maybe provided with a valve 15, of the ordinary or any preferredconstruction to control the passage of water therethrough.

Located below each of the lower groups 5, 6 and 7, are tubular burners16, each of which is provided in its upper portion with perforations 17,for the escape of gas or any suitable hydrocarbon which may be used asfuel for supplying heat to the generator. Each of the burner tubes hascommunication at one of its ends with a pipe 18, which leads to a supply(not shown) of gas or other hydrocarbon. Each of the pipes 18, hasleading therefrom a branch pipe 19, which communicates with a burner 20,located in an air supplying tube 21, each of which has communication atone of its ends with atmospheric air or a supply of air under pressure,not shown. Each of the pipes 21, which surround the burners 20, isprovided at its upper portion with a longitudinally extended slot oropening 22, to permit of the passage of heat and flames from the burner20, therein, and each of said air pipes is located under one of theupper groups 8, 9 and 10, and so as to discharge the heat from saidpipes and burners against the conduits 11, of the upper groups, in anovel manner, as will be presently explained. Each of the fuel supplypipes 18, is provided above its branch pipe 19 with a valve 23, andbelow said branch pipe with a valve 24, of the ordinary or any preferredconstruction, which are employed to control the supply of said fuel tothe burners 16 and 20, the latter as before stated being located belowthe upper groups and above the lower ones.

By referring to the drawings, it will be seen and understood that eachof the upper groups is communicatively connected to the group below thesame by means of a hollow connection 25, which connections unite theheaders 13, of the upper and lower groups adjacent to the fuel supplypipe. By this arrangement it is obvious that water and steam will flowfrom the pipes 14;, through the conduits 11, of the lower groups andupwardly through the connections 25, into the lower conduits 11, of theupper groups, from whence it will pass through hollow connections 12,which unite the conduits of each of the upper groups at their endsadjacent to the water supply pipe. Each of the upper groups has atone ofits ends,preferably that end adjacent to the uel supply pipe, a conduit11, which may lead to a container for the steam.

It will be observed by reference to Fig. 2 of the drawing, that each ofthe lower groups is, composed of three horizontally disposed rows ofconduits 11, while the upper groups are composed of two rows ofsimilarlydisposed conduits, but I do not desire to be limited to thenumber of conduits which shall compose each group, as

it is apparent that the number thereof may a be varied. It will also beseen in said figure of the drawing that the conduits in each group, bothin' the upper and lower series, f

are arranged in staggered relation to one another, and that the burnertube 16., in each of the groups 5,, an 7, is located below the spacebetween the lowermost conduits 11, of said groups, which conduits arelo.- cated side by side, yet in spaced relation to one another, while.the tube16, of the group 6, is located directly beneath the lowermostconduit 11, of said group. The same arrangement of the burners 20 isemployed with respect to the conduits of the upper groups 8, 9, and 10,and it is therefore apparent that the flames and heat from the I variousburners, will contact with the bottom and side surfaces of the conduits,and will also surround them, and that as the conduits are preferablyrectangular in cross section they will present a very large surface tothe actibn of the heat, thus enabling steam to be quickly generated andsuperheated. Each of the pipes 14:, is by preference extended verticallythrough openings in one of the ai upp y n r 2.1, t a p int n a o end ofthe groups, thus affording simple and e f n eans r upporti g; the. as

named pipes.

I s b u t a y the e vedssc i ed rangem of h urn rs. a ves. h a

can b app i t h g up independ ntly of one another, or that all of themcan be heated at the same time if desired.

It is further apparent that by providing the burner tubes 20, with theslotted air supply pipes 21, which latter pipes may communicate at oneof their ends with the atmosphere or with air under pressure, a moreintense heat will be provided for reheating or super-heating the steamin the upper groups of conduits.

It isIturther evident that the pipe section lt, for the supply of wateris connected to the lower group of conduits and is extended upwardly atone of the ends of a pair of the upper and lower groups, and that as theslotted pip-e -21, surrounds the burner tube 20, located bet-ween saidgroups, which burner tube is connected to the fuel supply pipe section18, and that as one of 1 the upper groups is connected to a lower groupby means of the connection 25, said parts will be arranged in. compactform and so that they can be moved in unison, or, in other words, theyare all connected together so that they may be located in acomparatively small space and at any desired point.

Having thus fully described my invention, 1 what I claim as new anddesire to secure by Letters Patent is i A super-heating steam generatorincluding a plurality oi superimposed groups of conduits, each groupcomprising a plurality of rows of conduits arranged in superim- Iposedrelation, the conduits of the respective rows of each group beingarranged in staggered relation, the, adjacent rows of the respectivegroups being spaced apart a distance in excess of the spacing of theconduits and of each row of each group being in communication, and theconduits'of the, up per row of the lower group being in communicationwith the conduits of the lower row of the upper group, means fordeliver- -ing water to' the lower row of conduits of :the lower group,an outlet communicating with the upper row of the upper group, and meansarranged beneath each group and fed from a common source for heating thecone duits of that particular group only.

In witness whereof, I have'hereunto subscribed my name this third day ofSeptemher A. 11.1912, in the presence of two sub:

scribing witnesses.
